十四、ContentProvider往通讯录添加联系人和获取联系人

在Android中，可以使用ContentResolver对通信录中的数据进行添加、删除、修改和查询操作。

在对联系人进行操作时需加入以下两个权限  

content://com.android.contacts/contacts 操作的数据是联系人信息Uri
content://com.android.contacts/data/phones 联系人电话Uri
content://com.android.contacts/data/emails 联系人Email Uri            

一、清单文件

xml version="1.0" encoding="utf-8" ?>
< manifest xmlns:android ="http://schemas.android.com/apk/res/android"
package ="com.ljq.contact" android:versionCode ="1"
android:versionName ="1.0" >
< application android:icon ="@drawable/icon"
